    @arhi I agree, it is an interesting idea to design without cables.

      made sense to me, we'll see, fedex normally arrive inside 7 days so .. not a long time to wait and not expensive (2$ for 5 pcb's, 15$ assembly+parts, 15$ fedex) ideal board to try out the jlcpcb system

        Have you ever had a DHL driver scream at you then throw a package at your face while shouting "Social distancing?"

        Yeah, me either. They do leave things at my door and run away though. Jumper for scale.20200925_091645.jpg

        Look at those tiny resistors. Aren't they cute? you could accidentally desolder them with an intense gaze. I'm going to do just that to R1 and at least once to an R2.

            Dry run looks super promising. I goofed though and realized I do not have any 24->5V USB-C power delivery units.

            Now I need to build out a male-male harness, throw this on my delta, solder a second board to the delta duet, and try a real run.

              @deadwood83 would be cool to have an integrated 5V regulator

              I used this one:

              https://www.amazon.de/PEMENOL-Einstellbar-Spannungwandler-Stromversorgung-Wirkungsgrad/dp/B07DP2MDJQ/ref=mp_s_a_1_2?dchild=1&keywords=5v+buck+converter&qid=1601061499&sprefix=5v+buxk+&sr=8-2

              They are super small. But I have to wire them with a cable directly from 24V

                @smoki3 it would still require traces back to the 24v input. Also, the coils used on those (and more often the B or C-lot mp1584) are intolerant of feedback on the 12/24v line. Not to mention the RF noise it generates and the extra heat to dissipate. When the fail, they fail open. If that overwhelmed the 3.3v stepdown on the pi it would probably damage the input buffers on the PCB; so then you're either doing micro soldering or putting on a whole new daughterboard just to avoid running one tap from the PSU and a dedicated 5V for the pi.. in addition to having to buy a new pi.

                Add that to quadrupling the PCB cost due to needing to stretch all the way back to the inputs and suddenly that mod costs Pi+PCB+Time+Risk to damaging mainboard. Add a voltage regulator after the input and the PCB SMT cost skyrockets due to small quantity. It's just not worth it and defeats the tiny form factor. One of my goals was to give people an option to add SBC support without having to redesign mainboard housings.

                In comparison, a 50W Meanwell 5V supply is ~USD $13 and includes a meshed RF-blocking shell (for the high frequencies that could interfere with comms); voltage regulation; transient handling; and is not exposed to feedback spikes from, say, a ceramic-potted heater cartridge.

                The design is fully open source. I won't ever put a cheap digital buck, but nothing stopping you from dipping a toe into PCB creation and doing it yourself. That's how I got started, and I highly recommend it. It's pretty fun!

                My 5v PSU and USB-C hookup should be here Wednesday. Kudos to the firmware team for the excellent work on the Duet2 SBC support. I have not been able to derive a synthetic test which causes it to fail where standalone does not. I still have 4 PCBs I am willing to send at the cost of postage to homes in the continental USA.

                      they sent me email few hours ago that they sent the package today, bit slower than I anticipated but still ok. Let's see how much time it takes for fedex to bring it here.

                      I ordered 5 boards, I need 3 and one will go to omni so I will have one spare, shoot me your address via pm... anyhow I need to test them first and that might take bit longer (as I'm one handed attm so everything is very slow till my right hand is back to "working and not hurting like a #$%^@$^%$" state)

                        It may be worth while for one of us in EU to order a batch from JLB ourselves can you post the full file set you sent to them for quoting and I can look into it.

                            @Dougal1957 the whole kicad project is attached to my original message, now, that handles the gerbers, I'll check if I stored the original bom and placement files (I think I killed them after the upload but they are easily regenerated 😄 there are only 4 parts on the whole board) ... anyhow, let's see if this works before we get more orders from jlcpcb 😄 and if there maybe is some smart change that can be done too 😄 ... I was thinking maybe a footprint for the 3A DCDC board to bring 5V to SBC ... also maybe 3V3 pin on the serial header too ... and maybe some gpio from the sbc to some relay tu turn external something on/off ?! ... tbh I made this mostly to quickly test jlcpcb than I really give enough thought in the board itself 😄 .... now after I had some time to think about it I'm getting ideas 😄 😄 😄 but wanna see if this barebone thing works or not before I start adding stuff 🙂 (and seeing if the jlcpcb works for me or not as I need a rather important project to design and if this works ok I'll use jlcpcb to do it, but if not I need to look elsewhere and design house dictate what parts I'll be using so...)

                              @Dougal1957 btw, just remembered I didn't export from kicad, I imported kicad project to online easyeda and ordered fromt there

                              https://easyeda.com/arhi.smece/duet2sb

                              I think you should be able to see it

                              btw, when you generate placement from easyeda the preview in jlcpcb show that U2 is rotated 180 degrees wrong. I let it go like that and then sent email to their support about it so they turned it properly. Then they explained that I should edit the placement file (it's text, comma separated) and rotate part myself till preview show it ok - for future projects

                                  @PCR that easyeda is what I ordered. it is not tested yet (boards shipped today so ..) and I have ideas for improvement but not put any on the paper yet (waiting for these boards to be tested first) so yes it is up2date

                                        Sorry, no news yet. Once I finish the PanelDueFirmware 3.2 release (hopefully the coming week) I will get back to investigating the problem with DueX attached. Though since I last tested a lot has happened in the firmware. Have you tested RRF 3.2-beta1? Is it still broken?

                                          Testet today again with latest official release.

                                          Still not able to home all axis at once (simple G28 command). The printer hang forever.
                                          All axis are homes with stall detection.

                                          Firmware flashing now seams to work well.

                                          Sometimes homing is working now. I will try a print later
